BMC Teammachine SLR 01 Six Bike

Some bikes are built to win sprints. The BMC Teammachine SLR 01 Six is built to win climbs. BMC's SLR platform has always centered on one goal — maximum lightweight performance — and the SLR 01 SIX delivers that mission with a Gen 5 01 Pro Carbon frameset, Shimano Ultegra Di2 electronic groupset, a 4iiii power meter, and BMC's own CR 40 carbon wheelset. At 7.8 kilograms for a size 54 complete build, it's a road bike engineered for the kind of riding where every watt matters and every gram counts.

The SLR 01 Gen 5 frame is built around BMC's 01 Pro Carbon — a high-modulus carbon layup developed at Impec Lab in Switzerland to achieve the stiffness-to-weight ratio that defines the SLR platform. BMC engineers TCC Race Compliance into the fork and frame, a technology that introduces controlled flex to absorb road vibration without any loss of pedaling efficiency. The result is a bike that stays stiff under power and smooth over rough tarmac — the kind of performance that matters most on long alpine climbs where road quality is anything but consistent.

BMC's Aerocore Design adds another layer of intent to the SLR's engineering. A pair of integrated carbon bottle cages are shaped to optimize airflow over the downtube and seat tube — keeping bottles in reduces drag measurably, which matters when you're pushing watts for hours on end. The ICS 2 stem integrates the cockpit with full stealth cable routing, and the BMC HB D4 01 Premium Carbon handlebar provides race geometry: 125mm drop, 80mm reach, and 6° of flare. Everything about this cockpit is purpose-built for riding fast uphill.

Design Benefits

1. Shimano Ultegra Di2 with 4iiii Power Meter
   Ultegra Di2 is Shimano's second-tier electronic groupset — but in real-world use, the difference between Ultegra Di2 and Dura-Ace Di2 is measured in grams, not performance. Shifts are instant, braking is precise through the hydraulic disc calipers, and the 11-34T cassette provides a climbing-friendly range without sacrificing top-end speed. The included 4iiii Precision Gen3+ power meter turns every ride into a data session, letting you track watts in real time and dial in pacing across long efforts — without adding $300–400 to the build cost after purchase.
2. BMC CR 40 Carbon Wheelset
   The CR 40 wheels are BMC's own 40mm tubeless-ready carbon rim, built on center-lock hubs. A 40mm depth sits squarely between a pure climbing wheel and a full aero wheel — keeping you aerodynamic on rolling terrain while remaining light enough for serious climbing. Continental Grand Prix TR tubeless tires in 28mm come pre-installed, giving you a fast, puncture-resistant setup that's road-ready out of the box.
3. TCC Race Compliance
   BMC's Tuned Compliance Concept targets specific areas of the frame and fork where controlled flex improves comfort without sacrificing stiffness at the bottom bracket and head tube — the zones where power transfer and handling precision matter most. Riders who spend hours in the saddle on rough pavement will notice the difference. It's not a cushioned ride; it's a precise ride that doesn't punish you over long days in the mountains.

Final Take

The BMC Teammachine SLR 01 Six is the entry point into BMC's SLR 01 family, and it's no compromise to say so. The frame and fork are built to the same 01 Pro Carbon specification as every SLR 01 in the lineup — the same carbon, the same geometry, the same SLR 01 Gen 5 architecture. Where the SIX steps back from higher builds is the groupset and wheels, trading up-spec components for accessibility at $7,299. For the rider whose riding is defined by long climbs, big cols, and days that demand a light and responsive race bike, the Teammachine SLR 01 Six is built precisely for that.
